If you call a car a boat, that doesn't make the car an actual boat because words have meaning. And so do names. Calling Larian's "BG3" doesn't make it a Baldur's Gate game when it doesn't portray any of the meaning that the existing Baldur's Gate series is known for.
And when Larian's "BG3" is a clone of the D:OS series, then it contains the meaning of that word - which makes it a D:OS game and not a BG game.
